I applied for the position through campus recruiting. They held a pre-social interview before the campus interviews. Campus interview was 30 minutes, one-on-one, behavioral questions, and very conversational since we have already discussed skills and such the night before. I got called in for an office visit the next day which was held two weeks later. The office visit consisted of a dinner the night before with audit associates and you get paired up with a "buddy". The next morning I met with one partner and two senior managers. All very friendly. Asked about my resume and had some behavioral questions. The hardest question is probably, "what questions do you have for me?" because everyone you meet asks you that question. By the end of the day, I was exhausted from thinking of and asking questions. They really want to make sure you are comfortable though and reimburses you for your travel costs.
